Document Summary
Chapter 26: club fungi: phylum basidiomycota (about 16,000 species) they have septate hyphae and include mushrooms, bracket fungi, puffballs, bird"s nest fungi, and stinkhorns. Sexual reproduction involves production of basidiospores within clublike basidia contained within a basidiocarp; asexual reproduction is rare and involves the production of conidiospores. Basidiocarps are fruiting bodies (e. g. , mushrooms and puffballs) composed of tightly packed dikaryotic hyphae whose walled-off ends become the club-shaped basidia. A basidium contains four projections; cytoplasm and a haploid nucleus enters to form four basidiospores. Stinkhorns have a slimy cap and attract flies by their bad odor to pick up and distribute spores. Rusts & smuts are club fungi that parasitize cereal crops (e. g. , corn, wheat, oats, and rye) and cause great economic crop losses every year. Spores of rusts and smuts are small and numerous, resembling soot. Some smuts enter seeds and exist inside the plant, becoming visible only at maturity.
